Categorical loudness scaling is a fast, clinically usable loudness measure.

Evidence

There are a number of techniques for measuring loudness perception (Florentine 2011 ); in this work we will focus on categorical loudness scaling (CLS). CLS is a task that has a well-studied relationship with hearing loss, uses category labels that are ecologically valid (e.g., “Loud”, “Soft”), can be administered in a clinic relatively quickly (< 5 min/frequency), and requires little training on the part of the tester/listener. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2512
